This originally started out as a question, but then I figured out the
answer (or should I say, "an answer"), so I'm sharing in the hopes
that this helps someone else out.
Suppose you have two packages that you want to ensure are installed,
and then use a require later on. I did it like this:
package { [foo, bar]:
ensure => installed
}
file {"/tmp/example.txt":
require => Package[foo,bar],
content => "Sample content"
}
However, if you then decide to add package "baz", you have to add it
in multiple places, which isn't a good idea. I'd rather edit it in one
single place.
The solution is to store the package names in an array.
$packages = [ foo, bar ]
package { $packages:
ensure => installed
}
file {"/tmp/example.txt":
require => Package[ $packages ],
content => "Sample content"
}
Now you can add package baz in the $packages definition, and away you go.
